The file 'Spool Rim 3D Printer Model' is (stl) file type, size is 1.4MB.
This is a rim for the cardboard spools that filament comes on in order to use them in an AMS that "requires" plastic spools. When cardboard spools are used and the filament gets low you will get lots of jamming errors or over tension errors. This allows the spool to rotate freely on the wheels without having to transfer filament, cut up the cardboard spools or buy extra stuff.
The most common is 200mm diameter but I had a couple spools where that was tight so I made a couple different sizes. They do better too tight rather than loose.
I'll add more as I get the files made.
